Definitions

  • the present invention relates to a building material obtained from plant residues, and having uses similar to those of wood, and to the process for obtaining it.
  • the present invention aims to provide a product which is compact and vacuum-free, and obtained by a simple process, from inexpensive raw materials.
  • the object of the invention is to provide a less expensive and more available material than solid wood, and yet capable of replacing it in all its uses, and even to be used in structures where the importance of the efforts does not allow the use of even the hardest woods.
  • the invention provides a building material obtained from plant residues, characterized in that it is formed from plant fibers impregnated with a binder and grouped in bundles, of parallel fibers, each bundle having the shape of an oblique parallelepiped, having four faces parallel to each other two by two and parallel to the fibers, and two end faces parallel to each other and making an angle of 30 to 60 ° approximately with the fibers, the packages being arranged in superposed layers , each layer comprising several packages of substantially the same dimensions and in contact with their end faces, the end faces of the packages of a layer being offset with respect to the end faces of the packages of an adjacent layer, and the packages being linked to each other using the binder that permeates the fibers, to form a block.
  • the vegetable fibers can be sugarcane, jute, hemp, flax, cotton or kapok fibers. Preferably, however, these are coconut fibers.
  • the binder is a polyurethane adhesive.
  • the invention also provides a process for obtaining a product as described above, and which comprises the following steps: - dip the fibers in the binder, - arrange in a mold the fibers impregnated with binder and grouped in bundles and layers, - press the fibers inside the mold, until at least partial polymerization of the binder, - if necessary, finish the polymerization and proceed with drying out of the mold.
  • the binder with which the fibers are impregnated is a one-component polyurethane adhesive.
  • the fibers are practically independent of each other in the mass of non-polymerized binder, they can bend and move relative to each other, in particular at the limits of the adjacent bundles, which has the effect of filling the voids between bundles, and to overlap adjacent bundle fibers.
  • coconut fibers which are very small in diameter: 0.10 to 0.40 mm.
  • Another advantage of these fibers is their resistance insects and other pests that attack wood or bamboo.
  • the block 1 is formed of a number of layers 2 each consisting of a series of packages 3 formed of parallel fibers.
  • Each package has the shape of a geometric volume limited by an upper face 4 and a parallel lower face, not visible, which extend from one side to the other of the block, two lateral faces of which only one 5 is visible and which coincide with the sides of the block, and end faces 6 which are, in the example chosen, inclined at approximately 45 ° on the plane of the upper and lower faces, this angle could vary, in practice, between 30 and 60 ° about.
  • packages 3 are prepared using fibers dipped in unpolymerized or incompletely polymerized binder.
  • the packages are placed in a mold, which, in the example chosen, has rectangular faces, the packages being arranged in successive layers, taking care to offset the end faces 6 from one layer to the other, to prevent formation lines of weakness, then a pressure is exerted on the mold so as to obtain a homogeneous block, and the assembly is left in the mold until sufficient hardening so that the polymerization can be completed outside the mold.
  • the material obtained is suitable for replacing wood, especially when it is intended to withstand great efforts. It is rot-proof, waterproof, resistant to bad weather, not reacting to large changes in temperature, unassailable by insects. It offers the advantage of being able to be worked like wood (sawing, sanding, varnishing, etc.). Its flexural strength exceeds that of reinforced concrete, its density is lower than that of water, its thermal resistance ranges from -20 ° C to 120 ° C. Its rot-proof and waterproof character and its variable forms depending on the molds used make it possible to advise it in the nautical and aeronautical fields.
  • Two workers can mold an average of 5 m3 per day, depending on the organization of the work, and even much more.
  • the figure shows a block 1 roughly in the shape of a parallelepiped. It should however be observed that the process makes it possible to obtain blocks of various shapes, and even of very complex shapes. It is enough to provide the mold accordingly.
  • the packages located far from the walls of the mold have roughly the shape of a parallelepiped, while the packages intended to be placed near the walls may have a different shape .
  • the packages are arranged so that the fibers bypass the cores provided for this purpose in the mold, or even wrap around them. It is obviously the same if the block must include inserts, for example metallic. The flexibility of the fibers allows, therefore, a wide variety of manufacturing.
